Answer:
part a: 52%
part b: 0.4
part c: 0.24
Step-by-step explanation:
For part one, you find the frequency of the number of people that are less that 20. You add the number of tics in each bar and you divide by the total.
so for part a it is (7+6+9+4)/ (7+6+9+4+4+12+8)
for part b you add up the values that are greater than 25(less than 35)
(12+8)/total
part c you find the number of people between 25 and 30
that's 12
over total
12/total

Step-by-step explanation:
T<span>he product of -2x^3+x-5 and x^3-3x-4 would look like this before simplification:
-2x^6 + 6x^4 - 8x^3 + x^4 - 3x^2 - 4x - 5x^3 + 15 x^2 + 20
Now combine all the like terms. For example, 6x^4 + x^4 = 7x^4.
Write the product in the simplest possible form, which involves combining like terms and arranging them in descending order by power of x.
